I don't eat much vegetables so I've started choking down v8 lately because... it's got to be good for me, right??

I use to have a problem eating veggies too. Went the V8 route also.

Now I just stir fry veggies with some stir-fry sauce. The veggies all kind of taste the same after they're stir fried. So now I'm able to eat vegetables I was never able to get down before (like brocolli).
I've actually grown a bit of a taste for them now too.
Throw in some chicken or beef, and it's on.

You've gotta define 'need' though. I've been lifting on a low-carb diet for ~3/4 of a year, with only enough carbs to keep me out of ketosis (60-100g /day) and maltodextrin in my post-workout shake. Carbs come in the form of low-carb vegetables and fruits, and a small amount of carrots/sweet potato.
